Practice making DIY- GC 00 94 - DDS signal generator
1. Function description:
Design based on STM32 microcontroller - DDS signal generator
Features:
Hardware composition: STM32F103C series minimum system board + LCD1602 display + AD9833 signal module + 4*4 matrix keyboard + multiple keys
1. Set the frequency value and the amplitude of the triangular wave and sine wave through the 4*4 keyboard (the amplitude of the square wave cannot be set to a fixed 4V amplitude), and the frequency setting range is 0~0.99999MHz. Amplitude setting range 0~3.3V (below 100mV waveform will be distorted, not recommended to be lower than 100mV)
2. Select the output waveform range through the 4*4 keyboard: three models of sine wave, square wave and triangle wave can be set
